The aim of the library is to enable customers to easily design high performance voice trigger and voice recognition systems, augmented with hands-free communication mode.

VoiceSeeker sits in between the applications processor (AP) and the microphones / speakers. VoiceSeeker notifies the AP whenever a voice trigger has been found and streams the noise-reduced (beamformed) audio to the ap processor.

High Performance

Due to our unique multi-microphone beamforming technique, we have managed to make the 4-microphone beamforming voice trigger will even outperform the Amazon Echo's 7 microphone setup.

The library is flexible enough to allow custom microphone configurations. However, microphone array design changes can have a large effect on the resulting system performance level, we always recommend consulting with us about any changes to our set of recommended geometries.

As a guideline, we have analyzed some common examples of arrays and their predicted beamforming performance in a diffuse noise field. This gives an indication of performance obtainable using different arrays. Follow this link (opens new window). As our beamforming is fully adaptive, these plots are meant to give an indication of attainable performance levels, they do not represent the actual performance in a given setup, which may be better or worse depending on the exact acoustical environment.
